The data given to the right includes data from 38 candies, and 77 of them are red. The company that makes the candy claims that 31​% of its candies are red. Use the sample data to construct a 95​% confidence interval estimate of the percentage of red candies. What do you conclude about the claim of 31​%? Construct a 95% confidence interval estimate of the population percentage of candies that are red.

Find a 90% confidence interval for the true proportion of people that eat frog legs, if in a sample of 732 people 65% eat frog legs.

CNN is conducting a poll, and wants to produce a 90% confidence interval for the proportion of all New York residents who favor legalizing recreational marijuana. Of the 602 randomly selected New Yorkers surveyed, 394 were in favor of the initiative. a.   With 90% confidence, the proportion of New York residents who favor legalizing recreational marijuana is between  BLANK and BLANK.  b.   Suppose that we survey 602 randomly selected Americans many times, and calculate a confidence interval for each group. About Blank . percent of these confidence intervals will contain the true population proportion of New Yorkers who favor legalizing recreational marijuana, and about BLANK   percent will not contain the true population proportion.

The figure to the right shows the results of a survey in which 1018 adults from Country​ A, 1025 adults from Country​ B, 1005 adults from Country​ C, 999 adults from Country​ D, and 999 adults from Country E were asked whether national identity is strongly tied to birthplace. Construct a 95​% confidence interval for the population proportion of adults who say national identity is strongly tied to birthplace for each country listed. The 95​% confidence interval for the proportion of adults from Country A who say national identity is strongly tied to birthplace is (____),(____) The 95​% confidence interval for the proportion of adults from Country B who say national identity is strongly tied to birthplace is (____),(____) The 95​% confidence interval for the proportion of adults from Country C who say national identity is strongly tied to birthplace is (____),(____) The 95​% confidence interval for the proportion of adults from Country D who say national identity is strongly tied to…
